18650154 ÷ 520 
Let's see how many times 520 fits into 18650154.

Step 1:
The number 520 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 520

On to step 2:
18 divided by 520 is 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 520

Advancing to step 3:
520 can be fit into 186 0 times, resulting in a remainder of 186.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 186, we end up with 186.
Include the next digit (5) from the dividend after 186, then repeat: 1865 / 520

Let's proceed to step 4:
If we divide 1865 by 520, we get 3 and a remainder of 305.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 1560 from 1865, we get 305.
Append the next digit (0) from the dividend to 305 and continue with: 3050 / 520

Moving on to step 5:
If we divide 3050 by 520, we get 5 and a remainder of 450.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we subtract 2600 from 3050, we get 450.
Append the next digit (1) from the dividend to 450 and continue with: 4501 / 520

Step 6:
4501 divided by 520 is 8 with a remainder of 341.
The next digit of our result is 8. 
Result so far: 358.0
The remainder is 341 after subtracting 4160 from 4501.
Fetch the next digit (5) from the dividend, attach it to 341 and continue: 3415 / 520

Let's proceed to step 7:
520 goes into 3415 6 times with a remainder of 295.
The next digit of our result is 6. 
Result so far: 3586.0
The remainder is 295 after subtracting 3120 from 3415.
Grab the next digit (4) from the dividend, add it to 295, then carry on: 2954 / 520

On to step 8:
The number 520 fits into 2954 5 times, leaving a remainder of 354.
The number 5 becomes the next digit in our result. 
Result so far: 35865.0
Deduct 2600 from 2954 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 9:
If we divide 3540 by 520, we get 6 and a remainder of 420.
Put 6 as the next digit of the answer. 
Result so far: 35865.6
If we take 3120 away from 3540, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 10:
520 can be fit into 4200 8 times, resulting in a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 35865.68
If we take 4160 away from 4200, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
520 can be fit into 400 0 times, resulting in a remainder of 400.
The next digit of our result is 0. 
Result so far: 35865.68
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
When dividing 4000 by 520, we get 7 with a remainder of 360.
Record the quotient 7 as the next digit in the result. 
Result so far: 35865.6807
If we take 3640 away from 4000, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 13:
3600 divided by 520 is 6 with a remainder of 480.
Record the quotient 6 as the next digit in the result. 
Result so far: 35865.68076
Subtracting 3120 from 3600 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 14:
The number 520 fits into 4800 9 times, leaving a remainder of 120.
The next digit of our result is 9. 
Result so far: 35865.680769
Deduct 4680 from 4800 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 15:
520 can be fit into 1200 2 times, resulting in a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 35865.6807692
If we take 1040 away from 1200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 16:
When dividing 1600 by 520, we get 3 with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 35865.68076923
The remainder is 40 after subtracting 1560 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 35865.68076923, and the remainder is 4e-08.
